Hi Rob,

It seems both shields use the same default chip select pin for the SPI communication, D10. This is likely why neither shield works when stacked.

Hope it helps.

And can I stack it as the following sequence: Arduino uno r4 + arduino proto shield + the lambda shield?

Hello James,

The Lambda Shield 2 require a stackable ICSP header which is not included in the Arduino Proto Shield.

Hope it helps.

Hello Christian I am new to using Nox Shield with Arduino board. I have an Arduino UNO R3 Set board. I have watched your instruction video many times I can see how you connect the wires from the Nox Sensor to the Nox Shield board, I am using a Bosch EGS-NX Sensor 24V but will be using it on cars.

Hi, An educational query for myself, looking at the schematic, there are pulldown resistors on the SPI lines, but literature I have read insists that there is no requirement for pull-down/pull-up resistors on SPI lines. Only info I could find is regards mostly using pull-up for certain scenarios. T...

Hello, I'm currently using a lanmbda2 Shield on an Arduino mega to tune my bikes. The disadvantage is that I constantly have to dismantle the lambda sensor to move it from one cylinder to another. I currently only have twin-cylinders but the latest is a four-cylinder. I'd like to know if it's possi...

Hi, Does Lambda Shield version 1 work with Arduino Mega? I can run it with Arduino Uno, but when I connect it to Mega, it doesn't draw any current. I need help urgently, thank you for your help. Hi Ugur, The original Lambda Shield was only compatible with the pins of Arduino Uno, specifically the S...

Hello Viteka32,

Unfortunately not, but you find the dimensions in the technical manual.

Hello CarUser,

Bosch are quite clear on this in the documentation: "Heating the sensor before the engine is started is not allowed."

Hope it helps.

Hello Michael, unfortunately the Lambda Shield apps (Windows, iOS, Android) are limited to AFR of 14.7.
